I am using rails v3.2.2 and I get a strange error when I try to load associated records.
The following is the Terminal input/output I get:
1.9.2-p318 :011 > Category.first
=> #<Category id: 1, ...>
1.9.2-p318 :013 > Category.first.articles
Article Load (0.2ms) SELECT `articles`.* FROM `articles` LIMIT 1
(Object doesn't support #inspect)
1.9.2-p318 :014 > Category.first.articles.first
Category Load (0.2ms) SELECT `categories`.* FROM `categories` LIMIT 1
NoMethodError: undefined method `scoped' for Category::Article:Module

In my Category
model I have:
class Category < ActiveRecord::Base
has_many :article_relationships,
:class_name => 'Category::Article::ArticleRelationship',
:foreign_key => 'category_id'
has_many :articles,
:through => :article_relationships,
:source => :article
end
In my Category::Article::ArticleRelationship
I have:
class Category::Article::ArticleRelationship < ActiveRecord::Base
belongs_to :article,
:class_name => 'Article',
:foreign_key => 'article_id'
end
How to solve the problem related to Object doesn't support #inspect
?
Note: In the same Category
model I have a similar statement like for Category::Article::ArticleRelationship
(it is related to an User
class through a Category::UserRelationship
class) and it does not cause problems.
